17. Disassemble the OEM strut assembly using a strut spring compressor. Remove the OEM coil seat & spacer ring from the OEM Strut. (See Photo # 16) Note: There are 4 Snap ring grooves located on the new Skyjacker strut body. The ring is installed in the 3rd groove from the bottom when shipped. This will yield 4" of lift. If 3.5" of lift is desired, move the snap ring to the 2nd groove from the bottom. If 3" of lift is desired, move the snap ring to the lower groove. The upper groove is only to be used when 4" of lift is desired, but aftermarket accessories have been added that weigh the front end down, ie. Winch, After Market Bumper, etc. At no point should more than 4" of lift be achieved using the components supplied. Install the spacer ring & coil seat on to the new Skyjacker strut. Once the coil spring seat retaining ring has been installed check all suspension components for any contact or interference. If suspension component contact or interference is present, lower the coil spring seat by lowering the coil spring seat retaining ring until no contact or interference is present.
